Biology Activities

What features distinguish living from non-living things? This demonstration is designed to challenge and provoke students to think about the definition of life. Observe the properties of organisms that a lifeless system can imitate.
Ever bite into an apple and hit a brown spot? What causes apples, potatoes, pears, and other foods to turn brown? Can it be prevented?
Diffusion of water into and out of cells is often demonstrated by treating cells with various concentrations of solutions and then examining them under a microscope. This activity allows students to view changes caused by osmotic pressure using a giant "cell" (chicken egg).
Use this activity to provoke discussion of an important social and health issue. Designed to simulate the transmission of a virus, the activity is based on a color change in a simple chemical reaction.
The membrane of a living cell plays a vital role in regulating what goes into and out of the cell. Some characteristics of cell membranes are discovered in this exercise.
Cells from the lining of the mouth provide an easy source of eukaryotic cells for observation. Plus, cheek cells are a great way to connect textbook drawings and models to life.
How do cell membranes regulate the internal composition of the cell? Use dialysis tubing to teach students the fundamental concepts of diffusion.
Discover the appearance and organizations of plant cells in different phases of the cell cycle.
Explore the effects of mutations: How does a change in one nucleotide affect the way a message is transcribed to RNA and translated to a protein?
A variety of factors may cause gene expression to start or stop. What effect does temperature have?
How does the architecture of a leaf affect its photosynthetic efficiency?
In this engaging simulation of electrophoresis, each student in your class becomes a nucleotide in a giant DNA model
One of the basic tenets of cell theory is that “all cells only arise from pre-existing cells.” In fact, new cells are formed by the process of cell division, which gives two genetically identical daughter cells.
